HSV color picker using Unity UI. Unity Forum Thread

Unity 2019 Unity 2018
Unity 2017
Unity 5.6
2019 is default, 2018 can import the assets just fine. 2017 and Unity 5 versions are on older branches.

Should be really easy to use. Just add the prefab to the canvas, hook up an event, and it's good to go.

    public Renderer renderer;
	public ColorPicker picker;
     
	// Use this for initialization
	void Start ()
	{
		picker.onValueChanged.AddListener(color =>
		{
			renderer.material.color = color;
		});
		renderer.material.color = picker.CurrentColor;
	}
 
	// Update is called once per frame
	void Update () {
 
	}

if you want to assign your own color first, just do this call and it sets the slider and picker to the proper selection.

    Color color = Color.green;
    picker.CurrentColor = color;

Can be toggled and sized as needed in settings.

On the color picker setup section.

Show Rgb: Show RGB sliders.

Show Hsv: Show HSV sliders.

Show Alpha: Show the alpha slider.

Show Color Box: Show the larger color selection box and color column.

Show Color Slider Toggle: Show the button to toggle the HSV and RGB sliders.

Show Header: Options to show the top header with color preview and hex code.

• Hide: Hide the top header.
• Show Color: Show only the color preview in the header.
• Show Color Code: Show only the color code in the header.
• Show All: Show the entire top header.

The prefabs starts with 4 colors in the color presets. This can be updated in the Setup section of the picker prefab.
Set the Preset Colors Id for different shared list between color pickers.
